Velocity is a JavaScript animation library used to create high-performance CSS and SVG animations. It functions as a CSS property interpolator and a spring physics engine, enabling the creation of smooth visual transitions and organic movement for web elements.
The project provides a programmatic interface for modifying vector attributes and 3D transformations through its SVG animation framework. It further distinguishes itself as an animation sequence orchestrator, allowing for the chaining of movements and the staggering of start times across multiple elements using promises.
The library covers a broad range of motion capabilities, including physics-based motion, complex animation sequencing, and high-performance UI transitions. It includes tools for managing animation playback and timing, as well as mechanisms for frame rate limiting to maintain consistent visual fluidity.
